In 2011 the award-winning renovation of the Grajska pristava (castle's outhouse) was completed, led by the Arrea Architecture bureau. It houses the Ormož Music School, a new multipurpose hall, and the ethnological and archaeological museum collections, and has turned the Ormož Castle into an outstanding cultural centre.

The Rajhenburg Castle dates back in the 9th century but the current construction derives from the 16th century. The castle that is called also Brestanica Castle is owned by the Municipality of Krško and was recently completely renovated with the support from the European Union's Cohesion Fund. Despite its rather sinister misuse during and after World War II it now features several museum collections, contemporary art exhibitions, a wedding hall, a museum shop, a restaurant and a café. It is managed by the Krško Culture House that runs a variety of cultural programmes.

As the Rajhenburg Castle was also a home to the only Trappist Monastery in the Slovenia, their rich legacy became an inspiration for the current exhibitions. The permanent exhibition on the Rajhenburg Trappists was prepared by the Brestanica Unit of the National Museum of Contemporary History already in the 1990s and was re-staged in 2013.
